Description

United States Patent PLATELET PRESERVATION James L. Tullis, Newton, Mass.
No Drawing. Application September to, 1952, Serial No. 308,951
4 Claims. (Cl. 167-78) This invention relates to the preservation of platelets outside the living body and, more particularly, to sterile therapeutically effective preparations containing platelets in concentrated form, suitable for in-vivo use as in the field of platelet deficiency therapy.
The primary object of this invention was to devise a means by which platelets could be stockpiled for in-vivo use in case of catastrophic atomic radiation, though such stockpiling for peace-time therapy is alone a worthy object. To this end, it was imperative that platelet integrity outside the human body be prolonged, inasmuch as prior to this invention the stability of intactnessin the sense of preservation of therapeutic eflectiveness-of platelets outside living bodies did not exceed three days. Further objects include the preservation of platelets in a form suitable for injection into a living body at high concentratio'ns, for therapeutic purposes.
In accordance with this invention, the duration of platelet integrity has been increased beyond the most optimistic expectations and now greatly exceeds the average in-vivo life span. No final figures on the ultimate time of satisfactory preservation can be given inasmuch as sufiicient time has not elapsed since the first platelets were successfully preserved to provide final data. Evidence thus far points to many months of satisfactory preservation.
This invention further provides a practical preservative medium for highly concentrated platelets; and the platelet-containing preservative is in water-soluble and,
hence, suitable and convenient form for direct injection into a living body.
Platelets preserved in accordance with this invention are derived from whole blood by any of a variety of separation methods. Though constituting no part of this invention, exemplary separation techniques are:
1. Whole blood treated to prevent clotting, as by the addition of citrate or other calcium sequestering agent, collected in a non-wettable surface sterile system and brought to a temperature near 0 C., may have its red and white cells sedimented with or Without the aid of 2. Whole blood may be passed, without the additionof citrate, over a cation exchange resin on the sodium cycle, some of which sites have been covered with calcium, resulting in a nearly quantitative separation from the whole blood of the platelets with the calcium of'the .blood. After the passage of the blood through the exchange resin, the platelets may be recovered fromthe exchange column by equilibrating the column with physiologi-c saline containing acetate ions and calcium complexing agents, all as described in an application of Edwin J. Cohn entitled Closed System for Continuous Separation of Components of Body Fluids, Serial No. 281,989, filed April 12, 1952.
The preservative medium of this invention may comprise an aqueous solution containing, per milliliters, about 0.2 gram of sodium acetate, about 5.0 grams glucose and about 0.9 gram sodium chloride. The wet platelet yield from 500 milliliters of whole blood (being the spontaneous sediment from the saline solutions after decanting the supernatant), is then gently stirred into this mixture which is maintained at about 4 C. To this mixture there is added sufiicient gelatin in a sterile pyrogen-free neutral aqueous solution so that, after standing, the composition will gel at a temperature of 4 C. In the case of a Knox gelatin of about 60,000 molecular weight and about midway with respect to gelatin frac- Gelatin Between 0.3 and 1.2 grams. Sodium chloride 0.36 gram.
Sodium acetate .08-O.2 gram. Carbohydrate (glucose)--. Not exceeding 2.0 grams. Platelets In excess of 200,000/mm.
By this procedure, approximately 50% of the original platelets of the blood can be recovered and discretely distributed through a medium having less than the volume of the whole blood. Since the concentration of platelets in average normal human blood is about 200,000 per cubic millimeter, the concentration is increased by a factor in the neighborhood of 5, but more important, of course, is their resulting stability for therapeutic purposes.
Where the separation of the platelets from the blood has taken place in a centrifuge, it is possible to use the preservative solution of this invention (before addition of the gelatin) as the eluting medium and, hence, avoid an intervening sedimentation step.
The gelled platelet-containing preservative can be stored at 4 C. and may be brought to a condition for in-vivo use simply by raising to body temperature, at which temperature the gelatin reverts to a non-viscid liquid.
It is understood that the preparations of this invention, when intended for in-vivo use, are prepared from sterilfl ized ingredients by aseptic techniques and using platelets derived from blood by aseptic and atraurnatic techniques.
The acetate anion acts as an anti-agglutina-te for the platelets. Other organic acid radicals function in a similar manner and may be added in water-soluble salt forniL. Only small amounts of such anti-agglutinating agents 1 need be present, as no benefits appear to be derived with concentrations about the rangeiof 0.2-0.5 gram per 100 milliliters.
V The glucose is an example of a hypertonicity-in-creasing agent. Other sugars or carbohydrates, whether nutrientor not, can serve with the'saline to impart hypertonicity to the solution. Preferably, they are included in such amounts as to provide a hypertonicity above 320 milliosmoles, the latter being approximately isotonic to body solutions. 7 7
An interesting observation resulting from the in vivo use of compositions of this invention in platelet deficiency therapy is the appearance of therapeutic effectiveness over and above that which would be expected solely from the number of injected platelets. This appears to be due to a thrombo-plastic activity of the gelatin-matrix itself and is possibly accounted for by the fact that, during storage,
water-soluble chloride and acetate salts, and glucose,
saidmatrix being maintained at a temperature of about 4 C., and substantially intact platelets discretely distributed throughout said matrix.
2. A therapeutic product, suitable for injection into humans at body temperature, comprising a sterile gel of the following ingredients:
Gelatin Between 0.3 and 1.2 grams. Sodium chloride .36 gram. Sodium acetate .08 to 0.2 gram. Carbohydrate Not exceeding 2.0 grams. Platelets In excess of 200,000 per mm. Water To total 40 cc.
maintained at a temperature of about 4 C., said product being liquid at human body temperature.
3. A solid matrix maintained at a temperature of about 4 C. but being liquid at human body temperature, comprising gelatin, water-soluble acetate salt, and viable .platelets discretely distributed throughout said matrix in a concentration exceeding 200,000 per mmfi, said matrix having a hypertonicity above 320 milliosmoles.
4. A solid matrix maintained at a temperature of about 4 C., but being liquid at human body temperature, comprising gelatin, water-soluble acetate salt, carbohydrate, chloride salt and viable platelets discretely distributed throughout said matrix in a concentration exceeding 200,000 per mm. said matrix having a hypertonicity above 320 milliosmoles.
